Hello. I recently moved my 2 children into the same room and they have bunk beds. My 5 year old sleeps on top and loves it. My 2 almost 3 year old sleeps on the bottom. I was also very nervous about putting my oldest on the top bunk. I was afraid she would fall or something. Now to my surprise my youngest ends up on the floor from the bottom bunk. Lol. The only thing I would suggest is to make sure the top bunk has the side railing so that they can not roll off in their sleep while they are getting used to sleeping up high in the sky. Thats what my daughter calls it.
